Dahlstedtia Malme (Leguminosae) is a neotropical genus, native to the Brazilian Atlantic Forest, and comprises two species, D. pinnata (Benth.) Malme and D. pentaphylla (Taub.) Burk., although it has been considered a monotypic genus by some authors. Leaf anatomy was compared to verify the presence of anatomical characters to help delimit species. Foliar primordium, leaflet, petiolule, petiole and pulvinus were collected from cultivated plants (Campinas, SP, Brazil) and from natural populations (Picinguaba, Ubatuba and Caraguatatuba, SP, Brazil - D. pinnata; Antonina, PR, Brazil - D. pentaphylla). Studies on leaflet surface assessment (Scanning Electron Microscopy), as well as histology and venation analyses were carried out of dehydrated, fresh and fixed... |

O nome popular "anileira" designa Indigofera anil L., I. suffruticosa Mill. e I. truxillensis Kunth, muito semelhantes quanto à morfologia externa. Este trabalho teve por objetivo avaliar se caracteres da semente e plântula apresentavam valor diagnóstico para este grupo, já que tais caracteres têm sido muito utilizados na Taxonomia de Leguminosae. A superfície e morfoanatomia de sementes e cotilédones foram estudadas por microscopias eletrônica de varredura e de luz, e as etapas do desenvolvimento das plântulas descritas. Embora as plântulas sejam semelhantes, caracteres de sementes (tamanho, forma, ornamentação da superfície, forma do hilo e tamanho do embrião) e cotilédones (forma, organização do parênquima lacunoso na nervura central e distribuição de... |

ABSTRACT Dipteryx, Pterodon and Taralea are legume genera known for secreting oils, produced in secretory canals and cavities, with medicinal properties. We analyzed the distribution, morphology and histochemistry of these glands in leaves and stems of Dipteryx alata, Pterodon pubescens and Taralea oppositifolia, three Neotropical species, using standard techniques for anatomy and histochemistry. Secretory spaces, i.e. secretory cavities and canals, exhibited a wide lumen and a single layer of epithelium. Digitiform epithelial cells, forming trabeculae protruding into the lumen, were seen in all three species. Secretory cavities with a rounded or oval lumen and secretory canals with an elongated lumen in longitudinal sections were found only in T.... |
